It is on 25 acres in the hamlet of Cherry Plain, Rensselaer County, a 35-minute drive from Albany. It has three bedrooms, three full bathrooms and two half-baths, including one in the basement. Highlights include solar panels on the roof, two office spaces, a screened porch, a first-floor master bedroom and a living room overlooking the in-ground, saltwater pool. There is a formal dining room, eat-in kitchen and an attached, four-car garage. Berlin schools, liquid propane zoned heat, central air, private well and septic system. The exterior is stone and vinyl.
